The doctrine of (historical) inclusion is a deceptively appealing but unbiblical message that minimizes the lostness of the lost and, as a result, diminishes the saving work of the cross. Telling unbelievers that they are already saved, righteous, and in relationship robs the gospel of its power to save those who believe. It does this by promoting a cerebral faith that is little more than an intellectual acceptance of an insurance policy whose main benefit is a ticket to heaven. But the most damaging aspect of this doctrine is that it stymies love. Instead of being invited into union with Christ, unbelievers learn that they are the unwitting participants in an arranged marriage. Jesus is not on the outside waiting to be invited in; He has already entered against their will and married them! It's a fait accompli that you had just better get used to. If unbelievers then exercise their freedom in the only direction left open to them – refusing to participate through unbelief – their husband might yet pursue the eternal equivalent of an honor killing.
Happily, the gospel of grace that Paul et al. preached is nothing like this! Jesus has not violated anyone's will but stands at the door knocking and waiting to be invited in. He will dine with anyone and everyone who accepts Him. For God so loved the world that He sent His Son Jesus to save everyone. He then sent the Holy Spirit to point people to Jesus. Whoever believes in Him shall not perish but enjoy eternal life in union with the Triune God. The life He offers is nothing like the one you were born with for it is His life. Jesus wants to live His life of unconditional love, divine favor, and supernatural power through you. To live like this is to experience heaven on earth here and now. It is knowing God – His love, His will, His joy and pleasure – today. And this life is available to all who would say, "Yes, Jesus!" Salvation is not an historical event. It is the present reality of Christ living in me. Now is the time of God's favor. Today is the day of salvation.
